Built for Swanage homes

Dorset property here means coastal villas, thatched villages and retirement bungalows — light-filled garden rooms are a major driver. That local context shapes what we recommend in Swanage — from glass specification to frame colour — before a single quote is written.

Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.

From Swanage we also serve Poole, Weymouth and Dorchester and the wider county — so if you're comparing quotes anywhere in Dorset, ours is free, fast and without obligation.

Roof Lantern Repairs in Swanage — common questions

Is condensation between the panes repairable?

The pane itself isn't — once a sealed unit's edge seal fails it's replaced, not resealed. The frame stays; only the glass unit changes.

When is repair not worth it?

When the frame itself has failed: non-thermally-broken early aluminium running with condensation, or softwood gone soft. We'll tell you straight on survey and price both routes.

My lantern glass has misted up — can it be fixed?

Yes — misting means the sealed unit has failed, not the lantern. We measure the pane, manufacture a matching unit (including self-clean or solar coatings) and fit it in situ, usually within a couple of weeks.

Water is dripping from my lantern — what's the likely cause?

Could be five things: ridge capping, hip junction, perimeter seal, kerb flashing or the flat roof itself, with condensation a sixth impostor. We trace the actual path before quoting, so you pay to fix the real fault.

Do you cover Swanage for installation?

Yes — Swanage is inside our standard Dorset coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Swanage on dedicated glass transport.

What's the lead time for Swanage?

Stocked standard sizes typically deliver to Swanage within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
